Added direct Telephreak access with KP + 777 + ST, DISA dialtone at KP + 2602 + ST for DTMF access and stacking experiments, and KP + 199 + ST for a 2600 Hz supervision test. Also documented a few alternate ways to access the system, including the Collector's Net, Free World Dialup, and direct Asterisk connection. See the first post in this thread for an updated listing.

Please do not abuse the Telephreak link.

For stacking, apply and remove 2600 Hz for at least 1 second, wait for the wink, then MF dial KP + 2602 + ST. When you hear the dialtone, dial DTMF 2602, wait for another dialtone and dial 2602, etc. up to 24 loops. On the last dialtone dial a PSTN number (10 digits only). Press a DTMF key on the originating phone to "flash forward". You can hear a click for each link in the stack on the terminating end. Hang up the originating end while listening to the terminating end. Hear a cheep of 2600 for each link in the stack as the call disconnects. Works only from originating end to terminating end.

You can also DTMF dial any of the other codes listed at the DISA dialtone, without the KP and ST, of course.

The 2600 supervision test places 2600 Hz into the SF trunk from the terminating end at busy signal and reorder timings. You can hear the action of the SF notch filter as it creates a beep for each application and removal of 2600. If dialed through a non-SF trunk, you would here a steady 2600 for each flash. The Asterisk DSP notch filter gives a brief 2600 chirp when 2600 is applied or removed. The reverse 2600 will not "blow off" or disconnect the call, as I have the supervision in that direction disabled to "goody" the arrangement (allow multiple call attempts, using 2600 Hz to reset the trunk without having to redial trunk access). The notch filter is still active, though.

I just added a three part Haxor interview with Joybubbles (famous and recently deceased phone phreak Joe Engressia). Each part is an hour long! It contains lots of great technical trivia from the old days of phone phreaking. The recordings sound like you're evesdropping on an old hacker conference line, rather than a straight interview.

I added all 16 "Sounds of Long Distance" recordings by Evan Doorbell from the Phonetrips web site to my ProjectMF server.

They are available via blue box by whistling off the connection and routing to the recordings with KP+NNN+ST, where NNN is 128-130 and 132-144 You can prefix the three digits with any area code and it will route just the same.

Very nice job, I assume you are the operator that I talked to? Enjoyed the recordings, I wasn't around for "back in the glory days" but, this is very fun, and I wish I had been. I'll continue playing around with it.. I assume there are easter eggs?

Yes, some Easter Eggs are in there! The easiest to find are the old intercept recordings I have been adding. KP+NPA+ST (NPA=one of the original area codes, with a 0 or 1 for the second digit) will play an authentic intercept from that NPA,if I have added it. KP+NPA+xx+ST will play a specific numerical recording from that NPA, using the original switching center ID. A list of these IDs is on the Phonetrips FTP web site.

Eaxmple:

KP+216+ST will play recording 216-02 recording as a default, as it's the lowest numbered recording I have for the NPA.

KP+21602+ST will play the same recording.

KP+21608+ST willplay another recording from the 216 NPA.

These suffixes can be mapped to specific switches and cities using the guide I mentioned at the Phonetrips web site.

In the Blue Box Bill of Materials XLS, http://projectmf.org/downloads/BOM.xls, it looks like the 1K Ohm, 1/6 watt, 5% Carbon Film Resistor model P1.0KEBK-ND is no longer being sold by DigiKey. Now, I've only just started learning about these kinds of things, and I know next to nothing, so I just wanted to check and see if I could use this a substitute, http://www.sparkfun....roducts_id=8980

We're still up 24/7, and have been for several years. Feel free to jump in.

You are correct, there is SF/MF support in the Asterisk and Zaptel code. However, it is only partially working. It also uses "spurt" signalling, where a burst of 2600 is used to indicate any supervision changes, rather than continuous tones. The ProjectMF patches and configuration settings change things to work more like the old R1 signalling system.

The patches were written for Asterisk 1.2, which is quite old now. I have never tried to apply them to a more recent build. The patches and configuration changes are documented on www.projectmf.org. Drop me a line if you have any questions.

To set up your own similar system, you don't need any special Asterisk/Digium card hardware, only two extra Ethernet ports, in addition to the one used for your network connection. I have only a single old PCI slot in my server. I bought a used dual-NIC card and use that for the 2600 trunks.

You need a source of timing for Asterisk, which can be supplied by a Digium card. I just use the "ztdummy" module which provides timing from the server. Works fine for the 2600 T1 trunk timing.
